JOHN \VOOLSEY SHAW', OF BERRYESSA, CALIFORNIA.

WASHER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 697,368, dated April 8,1902. Application filed August '7, 1901. S rial No. 71,184. (No model.)

To all whom, it may concern:

Be it known that LJonn WooLsEY SHAW, a citizen of the United States, anda resident of Berryessa, in the county of Santa Clara and State ofCalifornia, have invented a new and Improved VVasher-Fastener, of whichthe following is a full, clear, and exact descrip tion.

This invention relates to improvements in devices for fasteningpacking-rings or washers-such, for instance, as washers forhosecouplings or the like; and the object is to provide a simplefastening device that will firmly hold the washer and not interfere withthe passing of Water through the same.

Iwill describe awasher-fastener embodying myinvention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional view of a hose-coupling with a washer-holderembodying my invention applied thereto. Fig. 2 is an end view thereof.Fig. 3 is a perspective view of a washer or packing-ring and the fasteneand Fig. 4 is a side View of the fastener.

Referring to the drawings, 1 and 2 designate the members of ahose-coupling, the member 2 being internally threaded to receive thethreaded portion of the block on the end of a hose, which is designed toabut against the washer 3. This washer 3 consists of rubber or othersuitable flexible material. As a means for holding the washer in place Iprovide a fastener consisting of a strip of metalfor instance,spring-wirehaving a segmental or semicircular body portion 4,terminating at its ends in outwardly-extended points 5, designed to passthrough perforations in the wall of the Washer, and at the centralportion of the bodya coil 6 is formed which will add somewhat to theyielding nature of the fastener.

In operation the fastening deviceis inserted at the inner side of awasher and embedded at its body portionin a channel 7, formed in thewasher, so that the inner surface of the fastening device issubstantially flush or slightly within the inner surface of the washer,and thus the fastener will not interfere with the passage of waterthrough the washer.

The points 5, which extend outward from the washer, are designed toengage in the thread of the coupling-section 2, and by this means thewasher is held from displacement or outward movement when the hose isdetached from the coupling-section.

A fastening device made in accordance with my invention will be foundvery cheap to manufacture and is readily inserted.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.' A fastening device for a packing-ring or washer,comprising a segmental strip of metal having outwardly-turned endsdesigned to pass through the packing-rin g or washer from the inner tothe outer sides and projecting beyond the outer side, substantially asspecified.

2. The combination with a washer having a channel formed in its interiorsurface, of a fastener comprising a strip of resilient metal having asegmental body portion terminating inoutwardly-extended ends, the saidbody portion being designed to be inserted in the channel of the washer,substantially as specified.

3. The combination with a washer having an annularly-disposed channelformed in its inner wall, of a fastener having a body portion adapted tobe seated in said channel, a coil arranged in said body portion, andends extended outward from the body portion and designed to pass throughthe washer material.

4:. In combination with a washer, a fastener consisting of a strip ofmetal arranged wholly within the washer and having its ends turnedoutward and passed through the washer, substantially as specified.

5. In combination with a washer, a fastener consisting of a segmentalstrip of resilient metal embraced wholly within the circumfer- JOHNWOOLSEY SHAW.
